TEMPERATURE-REGLATING DEVICE FOR HEATERS.

Specification of Letters Patent.

Patented Jini?! 25, tttt.

Application filed ctober 27, 1914. Serial No. 868,796.

Abeing had to the accompanying drawings.

My invention 'relates to4 a heater adapted' for use with a brooder for raising?r voung chickens, and is particularly applicable to such use. and I have shown and will describe n1 v invention as thus applied.

In in v device the regulation is applied alternatively to a check draft for satisfying the flue. and to a' main draft for admitting air to the combustion chamber. 'lo render they regulation more automatic and certain, these two apertures are arranged in close proximity and in opposition to each other, so that a single valve theriuostatically controlled, may reciprocate between the two, coveringr one or the other aperture or occupying an)Y intermediate position between the two.

ln the accompanying drawings, Figure 1, is a vertical section of a broodci: heater havingl applied to it my invention. Fig. II, is a horizontal section along the line lll. Il, of

Fig. l. Fig. lll,'is a partial section on anl enlarged scale showing the automatic regulator iu detail.

The heater l. is provided with a grate :2, suitable Jr'or burning solid fuel and below which the ash pan 3. and the ash door i. The upper part oi' the heater constitutes the combustlon chamber proper, and is pro-- vided with a top 5. within which is set a magazine (3. with a feed openingr 7.

Surroundingr the upper part of 'the combustion chamber is an annular drum or heat radiator` 8. The combustion chamber communicates with the drum 8, by an opening 1l). v(See Fig. II). A fine 11. draws the heated products of combustion from the drum 8. depending-sleeve 1'2, forms a lower prolongation ot the flue 11, and compels the flue to draw from near the bottom of the drum S, through the lower aperture 13, ot the sleeve 12. aperture 13, is located the larger check draft aperture 14, by which the drum communicates directly with the outer atmosphere, permittin'fb1r the draft of the flue to be satisadjustment by the milled nut 31.

Just below this flue` jfied without the passage of air through the eombustlon chamber.

A large deticcting hood 15, in the .shape of a conical annulns is Set around, the top of the heater, for retaining the warmth of the heater within the space immediately snrrounding it as customary in broeder heaters of this type.

.tt the side of the heater which corresponds to the vposition of the aperture 1-1, there is provided a curved pipe .20, which enters the heater and communicatie with the combustion chamber by way oit the,

grate 2. By this pipe, is supplied thernain draft which passing through the pipe feeds the combustion. rl`he upper aperture 21, of this' main draft pipe 20, is in innnediate proximity to and in opposition tothe check draft aperture 141, heretofore described.y

Between" these two apertures is' the double ralve'QQ,.compi-13mg a @entrai stem 23, and

two disk shaped plates 21. The two disks. forni in substancev one valve capable of gov- The pivot 26, is sustained bv a fired ineniloer 2S, attached rigidly to the side ot the heater, as for example, by means oi the arm 29. to the pipe 20. An upright rod 30, threadodat the top, passes througir'the arm 25, netti the pivot, its relation thereto being capable fot 'lf' he lower end of this rod 30, is connected by a link 3:2. to a fulcrurn 33, set `in tixed relation to the member 28, upon which the parts just de-v scribed are all Supported. A. thermostat 35, is interposed between the fixed arrn 3G, in fixed relation to the member 2S, and the link 32. By the expansion of this thermostat the rod 30, is depressed, in turn depressing the Vvalve 2:?, until it seats itself upon theupper extremity of the main draft aperture 21. In this position the main draft 4is closed and the check draft wide open. AAs the air under the hood 15, cools, the thermostat contracts allowing the valve to rise until it comes into contact with the check aperture 14. ln the. l
